When Cron with "newsletter_send_all" this job code execute then its status became missed and pass message like below. currently using magento's defalt cron settings with UTC time. My Cron.php executed in every 5 minute. Please help me out on this curios issue.
exception 'Mage_Core_Exception' with message 'Too late for the schedule' in /home/test/public_html/app/Mage.php:595

Also made below modification in newslatter module's observer in core for testing purpose but still its not working
public function scheduledSend($schedule)
{
$countOfQueue = 1; // default 3 Modified on 14 Nov 17
$countOfSubscritions = 1; //default 20 Modified on 14 Nov 17
$collection = Mage::getModel('newsletter/queue')->getCollection()
->setPageSize($countOfQueue)
->setCurPage(1)
->addOnlyForSendingFilter()
->load();
$collection->walk('sendPerSubscriber', array($countOfSubscritions));
}
This happens when the scheduler finds pending jobs that were supposed
to be scheduled longer than the time configured in
'system/cron/schedule_lifetime'. By default this value is set to 15
minutes.
There are two different problems the may result in you seeing this
error:
Cron isn't configured to run often enough: If you don't trigger cron
often enough then the tasks start piling up and most likely tasks
will be too late for schedule at the point when they're being
executed by the scheduler. Instead of increasing the
scheduler_lifetime settings you should increase the frequency cron
is being called to */5 * * * * (every 5 minutes) or even * * * * *
(every minute).
You have long running cron jobs that will block the execution of
other jobs: In case you're importing data, indexing products,
generating reports or doing other long-running jobs via cron (which
is generally a good idea) other jobs will not be run in parallel
(unless you're running cron.php instead of cron.sh). This will
result in these jobs not being executed. Find out which jobs are
preventing others from running (by looking at the timeline view) and
run them in a different cron group. (look at this for more
information and check the features added to version >0.5.0 for an
easier way to configure and manage cron groups.

In Laravel, in my Kernel, I have:
protected $commands = [
Commands\SendRenewEmails::class,
];
/**
* Define the application's command schedule.
*
* #param \Illuminate\Console\Scheduling\Schedule $schedule
* #return void
*/
protected function schedule(Schedule $schedule)
{
// $schedule->command('inspire')
// ->hourly();
$schedule->command('renew:emails')
->daily();
}
The said function renew:emails, works as intended if I run this manually trough Artisan.
And in my crontab I have:
* */8 * * * cd /path-to-my-project && php artisan schedule:run >> /dev/null 2>&1
I have this to run every 8th hour, instead of every minute at * * * * *, since this is live for testing, and just to ensure that the task wasnt run every minute.
So how does Laravel know, when to run the daily job on the kernal, and when does this happen?
From this setup (which seems to be the basic setup for cronjobs in Laravel, but to run every minute instead of every 8th hour), there is no logs (that I can see), and no table in DB to keep track of this.
So if I where to set my cron to * * * * *, how does Laravel know not to run the scheduled job every minute, just because I have put ->daily(); at the end of the job?
And when I have daily();, at what specific time is that? And at specific what time is hourly();?
TL;DR:
How does Laravel know not to run the same jobs again if it is not supposed to, for example with daily(); rule? Where is this information stored? How can I be certain that a job with rule daily(); wont run every minute if my cronjobs std:out's php artisan schedule:run every minute?
Under the hood, the Laravel Scheduler uses https://github.com/dragonmantank/cron-expression to determine if a command or job is scheduled to run at the given minute the schedule:run is called.
Each task you schedule translates to a cron expression, which is then passed into the package. A method called isDue is then run against that expression to determine whether or not it should run. So, if you set a task to run hourly, then isDue will yield true at the top of the hour, and Laravel will execute to the task within the cron cycle.
As such, the information does not need to be stored anywhere, as determination is done on the fly.
This might also lead you to wonder what might happen if you have a long-running task that might take longer than the interval. This is where withoutOverlapping comes into the picture. When called, it creates what is known as a mutex, which is similar to a 'lock' of sorts (see What is a mutex? for more information), when the task is initially run. If a mutex already exists for a particular task on subsquent cycles, it means that task is currently running in another cycle, and should not be triggered again in this one.
Where are mutexes stored? Simple: Laravel stores them in a cache, and when a mutexed task is finished, the mutex is removed from the cache. And so the cycle continues.
I could go into much further detail here, but I think this answers your question for the most part.
I have an annotated method width #Scheduled with an cron of */15 * * * * ? (run each 15 seconds).
Sometimes this process take more than 15 seconds to run.
Is there any way to avoid the call of the #Scheduled if it's already running?
My workaround currently is a flag field in the class to signal if the process is running, and if it is marked the code exits before execute the main code.
I think it's already the case, if the first job has'nt finished, the second will not start.
See :
How to prevent overlapping schedules in Spring?
If it isn't working, you can also use an AtomicBoolean to check if you must start the process or not.
I'm trying to run a cron on start-up and then midnight every day from that point.
I'm bound by Dashing to use Rufus Scheduler 2.0.24, in which I can't use 'first_in' with the cron command. The command in 3.x I want to replicate is like so...
scheduler.cron '00 00 * * *', :first_in => '0' do
I'm wondering if there is any way around this?
I found this which describes a similar issue - but this will only run the cron at the first instance of the specified allotted time and not immediately.
a plain way of doing it would be:
job =
proc do
puts "hello"
end
job.call
# run it right now
scheduler.cron('00 00 * * *', &job)
But maybe this one is more readable:
job =
scheduler.cron '00 00 * * *' do
puts 'hello'
end
job.block.call
# run it right now
scheduler.join
Thanks for posting a new question, it made everything clear. The question at Rufus Scheduler :first_in option unknown with cron is a bit different.
I know this is about rufus-scheduler 2.0.24, but I'd like to point to a new feature in 3.3.x: https://github.com/jmettraux/rufus-scheduler/issues/214 where you can do job.trigger_off_schedule and it invokes the job right now if overlap, mutex and other job options allow it.
Back to 2.0.24, the shortcut shown above has no refinement, it will run the block right now. The block might already have an instance running now, imagine you have the schedule set for "midnight every night" and you happen to restart at midnight. Hence, I think the first solution above, is best, because it triggers then schedules.
Like a lot of users i've some problems configuring Magento cronjobs (my cartrules doesn't update properly on Magento 1.8.1. I also modified my cron.php adding $isShellDisabled = true;).
A tried a lot of things, but it doesn't work. Installed AOE scheduler, and i see all my tasks as pending!
My hosting let me to call cron.php once a day (3 am, and it's working, becase it generates the tasks at that time), so i'm wondering if is useless having settings like this:
Generate Schedules Every 15
Schedule Ahead for 1
Missed if Not Run Within 60
History Cleanup Every 120
Success History Lifetime 1400
Failure History Lifetime 1400
If i run manually the cron.php, it generates tasks for a hour, all pending (for example, my cart rules XML are set to update every 15 minutes, so i get 4 cartrules tasks)
If i run it again (after few minutes), all tasks between this time change form Pending to Success.
So, have i to call it at least twice a day? Or i have to change my cron settings?
thank you for the help
Use this cron expression for each hour:
<cron_expr>0 * * * *</cron_expr>
This will make it run at 12.00, 1.00 and so on.
If you want to make it run at 12.30, 1.30 and so on replace 0 with 30
I have a spring application that uses quartz cron trigger. I have given the following for frequency 0 0/20 * * * ?.....once every 20 min. But i want the first one to run immediately. Right now, when I start the application, it runs after 20 min. I was hoping it would run asap and then after 20 min.
Thanks in advance.
It sounds like you want to use an interval trigger (SimpleTrigger in Quartz can do the job).
The CronTrigger wants you to specify the minutes at which to run.
So your trigger schedule says: start at 0 minutes, and run every 20 minutes after that until the hour is over. Then start at 0 again.
But with the SimpleTrigger, you say - start now and run every 20 minutes.
Here is a tutorial on SimpleTrigger:
http://quartz-scheduler.org/documentation/quartz-2.x/tutorials/tutorial-lesson-05
Here is a tutorial on CronTrigger:
http://quartz-scheduler.org/documentation/quartz-1.x/tutorials/crontrigger
You don't need CRON expression (and Quartz at all!) to run given code every 20 minutes. Just use fixed rate (Spring built-in):
#Scheduled(fixedRate=20 * 60 * 1000)
That's it! By default first invocation happens immediately, second after 20 minutes. Since Spring 3.2 you can even say initialDelay=10000 to run for the first time after exactly 10 seconds.
If you really want to use Quartz, check out SimpleTrigger.
